DPS-305 Adjustable DC Power Supply 0-30V 0-5A LED Display

DPS series digital input adjustable DC power supply, LED Display Mobile phone repair power test regulated power supplyDue to the voltage value is a digital keyboard input, shorten the voltage setting time, completely overcome the traditional potentiometer adjustment poor contact caused by voltage instability phenomenon. The internal power supply containing electronic switch, can conveniently open the output load.Input voltage: 110V/220V ±10%50/60HzOutput power: DPS-305BF 0 to 30V 0-5A DPS-305BM 0 to 30V 0-5AOption 1: DPS-305BM: BM: Four-digit display accuracy ±0.001A (1mA)Option 2: DPS-305BF added function: BF: Five digit display，accuracy±0.0001A (0.1mA)Power sound alarm functionMobile phone signal testMore curren digit displayOption 3: DPS-305CF added function: Five-digit display, newer version more than DPS-305BF, added Memory storage and password Memory lock function.added DC power Cable: 44 pcs power convert cablesValue added function: a quick call 10 groups of voltage and current data and storing the user required 10 groups of voltage and current data, password lock keyboard, prevent misuse or vandalism operation.Specification : 1: rated working conditions and dimensionsPower supply voltage 220V + 10%50 / 60Hz (110V need to order)Working conditions: 0-40 temperature relative humidity 80%Storage temperature: - 10-70 C 70% relative humidityDimensions: 265 x 128 x 150mm (D * W * H)2: Regulated state parametersThe voltage output from 0 to 30V can be continuously adjusted ( To distinguish the value of 0.1V )The precision of output voltage: + 0.1VVoltage stability: < 0.01%+3mvLoad stability: < 0.01%+3mvRecovery time: 100uSRipple noise voltage: < 1mVRMS ( 5Hz-1MHz )Temperature coefficient: < 300PPM / C3: A constant current state parametersConstant current value: 305 CM 5A Ma constant current maximum 500 mA303CM 3A Ma constant current maximum 500 mAConstant current output current from 0 to the nominal value of continuous adjustable ( to distinguish the value of 0.01A )Constant current output accuracy: + 0.01A ( MA constant current precision: + 1mA)The current stability of the < 0.1%+3mALoad stability < 0.1%+3mARipple noise current < 3mARMS4: Current and voltage display accuracyVoltage display accuracy: + 0.1V ( constant current state )Current display accuracy: + 0.01A ( constant pressure )Ma current display accuracy: + 1mA ( constant pressure )5: Storage capacityStorage and call ten current, voltage data ( 305 / CM )Initial has been deposited in the data: 1 keys ( 3V ) 2 ( 5V ) button button 3 ( 9V ) 4 ( 12V ) 5 button button button ( 13.8V ) 6 ( 15V ) 7 ( 18V ) 8 button button button ( 19V ) 9 ( 20V ) 0 ( 24V ) current key value is 5A, the user can arbitrarily settings change the desired voltage and current.6: A voltage step range10V / 1V / 0.1V lifting voltage stepThree panel featuresIn 1, the front panelCurrent display windowVoltage display windowData entry keyboard ( double function keys are: 0 / mA decimal point / latch / ENT / password 4 / stepper7 / 8 / 9 step step / step / step 2 / 1 step 3 / step )Constant voltage / ENT indicating lampConstant current lampOutput indicatorMa status indicatorPower switchOutput ports:" -" negative polarity ( black )GND: ground earthing terminal ( green )Output ports:" +" the positive ( red )
